我想自定义android编辑文本，以便在外部单击时，如果文本太长，它将自动滚动回第一个并在末尾显示三个点。我已经对其进行了定制以尝试使其运行良好但尚未优化，请参考它，如果可能的话，给我一个更优化的方法。


class CustomTextInputEditText(context: Context, attrs: AttributeSet) :
    TextInputEditText(context, attrs) {
    private var dotsString: String? = null
    private var storeString: String? = null
    private var mWidthMeasureSpec: Int = 0
    override fun onMeasure(widthMeasureSpec: Int, heightMeasureSpec: Int) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec)
        Log.e("CustomTextInputEditText", "onMeasure 1: $mWidthMeasureSpec")
        mWidthMeasureSpec = MeasureSpec.getSize(widthMeasureSpec)
    }
    override fun onSizeChanged(w: Int, h: Int, oldw: Int, oldh: Int) {
        super.onSizeChanged(w, h, oldw, oldh)
        Log.e("CustomTextInputEditText", "onMeasure 2: $mWidthMeasureSpec")
        mWidthMeasureSpec = width
        setText(text, BufferType.NORMAL)
    }
    override fun setText(text: CharSequence?, type: BufferType) {
        if (!isFocused) {
            if (!text.isNullOrEmpty()) {
                val tmpString = text.toString()
                val textWidth = this.paint.measureText(tmpString)
                Log.e("CustomTextInputEditText", " textWidth = " + textWidth)
                Log.e("CustomTextInputEditText", " mWidthMeasureSpec = " + mWidthMeasureSpec)
                storeString = tmpString
                dotsString = tmpString
                if (mWidthMeasureSpec > 0 && mWidthMeasureSpec <= textWidth + context.convertDpToPx(69f)) {
                    if (dotsString?.length!! >= (mWidthMeasureSpec / textWidth * tmpString.length - 5).toInt() && (mWidthMeasureSpec / textWidth * tmpString.length) >= 5)
                        dotsString = tmpString.substring(0, (mWidthMeasureSpec / textWidth * tmpString.length - 5).toInt()) + "..."
                }
                Log.e("CustomTextInputEditText", "setText: $dotsString")
            }
            Log.e("CustomTextInputEditText", "not focus: $dotsString")
            super.setText(dotsString, type)
        } else {
            Log.e("CustomTextInputEditText", "focus: $dotsString")
            super.setText(storeString, type)
        }
    }

    override fun onFocusChanged(focused: Boolean, direction: Int, previouslyFocusedRect: Rect?) {
        super.onFocusChanged(focused, direction, previouslyFocusedRect)
        if (focused) {
            setText(storeString)
        } else {
            val tmpString = text.toString()
            val textWidth = this.paint.measureText(tmpString)
            storeString = tmpString
            if (mWidthMeasureSpec <= textWidth) {
                dotsString = tmpString.substring(
                    0,
                    (mWidthMeasureSpec / textWidth * tmpString.length - 10).toInt()
                ) + "...";
                setText(dotsString)
            }
        }
    }
    fun getRawText(): String {
       if (storeString == null)
           return ""
        else
           return storeString!!
    }
}

我的 xml

  <com.google.android.material.textfield.TextInputLayout
                android:id="@+id/til_select_address"
                style="@style/TextInputLayoutStyle"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:paddingStart="@dimen/margin_10"
                android:paddingTop="@dimen/margin_16"
                android:hint="@string/select_address"
                android:paddingEnd="@dimen/margin_10">

                <vn.leaftech.f99fruits.utils.custom_view.CustomTextInputEditText
                    android:id="@+id/edt_select_address"
                    style="@style/TextInputEditTextLayoutStyle"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:singleLine="true"
                    android:textCursorDrawable="@null"
                    android:paddingEnd="@dimen/margin_24"
                    android:ellipsize="end"
                    android:lines="1"
                    android:text=""
                    android:maxLines="1"
                    android:focusable="false"
                    android:fontFamily="@font/opensans_regular"
                    android:scrollHorizontally="true"
                    android:textSize="@dimen/margin_16"/>


            </com.google.android.material.textfield.TextInputLayout>

我尝试了下面的代码，但它不起作用：

 android:lines="1"
    android:scrollHorizontally="true"
    android:ellipsize="end"
    android:singleLine="true"
    android:editable="false"
